摘要： A broadband spectrum analyzer for radio frequency and microwave signals. The signal to be analyzed modulates an optical laser beam through an electro-optic modulator. The resultant modulated beam thus comprises light at a frequency (carrier frequency) corresponding to the wavelength of the laser beam and frequencies close to the carrier frequency corresponding to the frequencies representing the modulating signal. The modulated beam is expanded to produce a beam with light traveling in a large number of directions within a narrow angle. The expanded beam illuminates the aperture of an etalon. The etalon functions as an optical filter passing only portions of the beam which enter the etalon at an angle such that the distance traveled by the light within the etalon equals an integral number of wavelengths. Thus, different frequencies pass through the etalon at different angles. The output from the etalon is collected by a video camera for display and interpretation. This new approach allows a larger instantaneous bandwidths to be analyzed than is possible with current systems, and allows a simple video camera to be used for observation of the spectrum of interest.

摘要： Small changes in material properties of a work piece are detected by measuring small changes in elastic wave velocity and attenuation within a work piece. Active, repeatable source generate coda wave responses from a work piece, where the coda wave responses are temporally displaced. By analyzing progressive relative phase and amplitude changes between the coda wave responses as a function of elapsed time, accurate determinations of velocity and attenuation changes are made. Thus, a small change in velocity occurring within a sample region during the time periods between excitation origin times (herein called "doublets") will produce a relative delay that changes with elapsed time over some portion of the scattered waves. This trend of changing delay is easier to detect than an isolated delay based on a single arrival and provides a direct measure of elastic wave velocity changes arising from changed material properties of the work piece.

摘要： A system and method for investigating rock formations outside a borehole are provided. The method includes generating a first compressional acoustic wave at a first frequency by a first acoustic source; and generating a second compressional acoustic wave at a second frequency by a second acoustic source. The first and the second acoustic sources are arranged within a localized area of the borehole. The first and the second acoustic waves intersect in an intersection volume outside the borehole. The method further includes receiving a third shear acoustic wave at a third frequency, the third shear acoustic wave returning to the borehole due to a non-linear mixing process in a non-linear mixing zone within the intersection volume at a receiver arranged in the borehole. The third frequency is equal to a difference between the first frequency and the second frequency.

摘要： In position-only shading, two geometry pipes exist, a trimmed down version called the Cull Pipe and a full version called the Replay Pipe. Thus, the Cull Pipe executes the position shaders in parallel with the main application, but typically generates the critical results much faster as it fetches and shades only the position attribute of the vertices and avoids the rasterization as well as the rendering of pixels for the frame buffer. Furthermore, the Cull Pipe uses these critical results to compute visibility information for all the triangles whether they are culled or not. On the other hand, the Replay Pipe consumes the visibility information to skip the culled triangles and shades only the visible triangles that are finally passed to the rasterization phase. Together the two pipes can hide the long cull runs of discarded triangles and can complete the work faster in some embodiments.

摘要： A system and a method includes generating a first signal at a first frequency; and a second signal at a second frequency. Respective sources are positioned within the borehole and controllable such that the signals intersect in an intersection volume outside the borehole. A receiver detects a difference signal returning to the borehole generated by a non-linear mixing process within the intersection volume, and records the detected signal and stores the detected signal in a storage device and records measurement parameters including a position of the first acoustic source, a position of the second acoustic source, a position of the receiver, elevation angle and azimuth angle of the first acoustic signal and elevation angle and azimuth angle of the second acoustic signal.

摘要： A method and apparatus for making rolls of wave cut bags, and a roll of bags is disclosed. A film is weakened along a generally straight line in a generally cross machine direction. The film is also weakened a wave shape, and the wave shape weakenings are alternated with the straight line weakenings. The film is folded in a cross machine direction, and the straight line weakenings are separated to form bottoms of adjacent bags. The bottoms of adjacent bags are preferably overlapped, although they need not be. The wave shaped weakenings are preferably separated (although they need not be) to form wave shaped tops of a adjacent bags. If separated, the wave shaped tops have a longer portion and a shorter portion, and the longer portion is between, in the machine direction, the longer and shorter portion of the adjacent wave shaped top.
